The object of this invention is to provide a. novel type of safetyrazor.

The invention involves a blade holder and a handle which are connectedin a novel ad- 5 justable manner so that the blade holder can beadjusted from a shaving position into the plane of the handle.

It is a feature of the invention to lprovide means for operativelyconnecting the blade 1o inthe blade holder, with the handle, so thatwhen the blade holder and handle are adjusted to various diEerentpositions, the blade will be actuated b such adjustment-into variouspositions in the blade holder.

Thus, in the most specic form of the invention, it is a feature toprovide means whereby on one -character of relative adjustment of theblade holder and handle, the blade will occupy a shaving position, andon another character of adjustment, the blade will be retracted into theblade holder, and on still another adjustment, the blade will beprojected'from the blade holder. It is a further feature to provide ablade holder, as set forth, which is readily opened or adjusted forquick removal of the blade when necessary and wherein the operativeconnection of the blade with the holder will be establishedautomatically merely by the insertion of the blade into the holder.

.The device of my invention also includes a novel form vof blade which Iclaim as new, as an article of manufacture.

The invention has many other objects and features which will be morefully described in connection with the accompanping drawing and whichwill be more particularly pointed out in and by the appended claims.

In the drawing:

Like characters of reference designate similary parts throughout thedifferent figures of the drawing.

Reference will first be made to Figs. 5 to 9 for the purpose ofspecicall describing the type of blade holding mem er or blade holderherein shown as embodying my invention.

Said blade holder includes what I lwill term a base or base plate 1provided with blade receiving and holding means in the form of lateralflanges 2.. rlhe'inner faces 3, of these flanges converge, as shown inFig. 9, so that when a clamping device, to be presently described, isforced between said flanges, the latter will snap over and hold saiddevice. The base plate has a face 4, which I will term the blade lface,andan opposite face 5, which I will term the handle face. The shavingedgev of the base plate is provided with the usual comb or guardcomposition with respect to posed of teeth 6, which may be formedintegral with said plate.

I have provided a form 4of blade which is shown in-Figs. 10 and 11, andwhich consists of a body 7, having a cutting edge 8, and provided withactuating means preferably in the form of a slot 9. This slot 9, asshown, is a linear slot that is not only parallel with the cutting ed ebut is disposed remote therefrom and re atively closer to the base edge10 than tothe cutting edge 8. 'In

accordance with my invention, this blade may be of the paper thicknessso as to be cheap enough to be discarded, after a few usages, or it maybe of a thicker stock that'will take repeated sharpening. i

Now, reverting to Fig. 9, it will be seen that the blade 7, ts againsttheface 4 and between the flanges 2, the clearance between the latterbeing suicient for relative movement of the blade with respect to theblade holder.

Said blade holder includes blade clamping means which, in the formshown, is embodied in a leaf 11 that is hinged at 12, to the rear ends13, of flanges 2, so as to be swun into or out of clamping relationftothe blade As shown in Figs. 5 to 7, the leaf is closed and in Fig. 9,the same is open. The lateral edges 14, of said leaf 11, are parallel,and when forced between the converging edges 8, the leaf will snap intoand be held in a blade clamping position. However, many other expedientsmay be devices to perform this broad function and I do not wish to belimited to the form shown except for such limitations as the claims mayimport. I prefer to hinge the leaf 11, to the base plate 1, as in sodoing, I am always sure that the free edge 15, of said leaf, will alwaysbe in predetermined relation with the guard, when said leaf is closed. A

Reference will next be made to an operating member intermediate thehandle and the blade and which member is Inounted in the blade holder.

Said member is shown in the form of a disc 16 which is peripherallyshouldered at 17, in a complementally formed shouldered opening in thebase plate 1, so that said disc may be rotatively adjusted. Thisshouldered mounting, which is clearly shown in Figs. 5l

to 7, prevents the disc from moving toward the-blade, from its normalposition `and the blade side or face of the disc 16 is flush with theblade face 4, of plate 1. On its blade side or face, said disc isprovided with an operating pin 18, which is adapted to slidably engageslot 9, of blade 7. Said pin 18, is

preferably of sutlicient length to extend past and through blade 7. Ipreferably provide leaf 11, with an arcuate guide slot 19 into which thefree end of said pin 18 projects in order to assist in guiding said pinand to prevent any binding action during adjustment of said disc.

Said disc 16, is of a thickness to ldispose its remaining facesubstantially flush with what I will term the handle side of plate 1, aswill be seen from Figs. 5 to 7 and projecting from and mounted on saidhandle face are two journals 20. A handle member 21 hasa reduced shank22 that fits between said journals 20 and a suitably fixed pivot pin 23,pivotally unites said handle with said disc. It will now be seen that Ihave rovided a connection between the blade hol er and handle whichcomprises a combined swivel and pivotal connection, and lthat a part ofthis connection is operatively associated with the blade.

Before describing the operation, I will refer to a feature of theconstruction'which not only functions Vto hold the disc'in posi-A tionbut which additionally functions to hold the handle in differentadjustive relation to lthe blade holder.

A A spring metal sheath retainer is indicated at 24, and that edgenearest the guard 6,is suitably secured to the handle face of the baseplate, 1, leaving the remaining edges v25, 26 and 27, free fromengagement with said plate 1 and in suitable spaced relation thereto, as

I have provided means, which for the present illustration, and purpose,may consist of a small link 30,- suitably attached to the 'holder at 31,and to the handle t 32, and which attachments may be disconnected whenthe holder is to be adjusted into any of the positions shown in Figs. 1to 3.

Thus it will be seen that the disc and handle may readily be detachedfrom the blade holder by springing the sheath 24 sufficiently to releasethe disc 16 from the base plate 1. With such disconnection of the parts,it will be clear that with the blade holder opened, as shown in Fig. 9,the whole structure is rendered accessible for cleaning or renewalpurposes. In order to facilitate the holding' of the handle and bladeholder in the various relative positions shown, I consider it a featureof my invention to bend the corner portions 33 and 34, of the sheath 24,downwardly, j

as shown, so thatthe handle will be frictioning than any other safetyrazorofthis type,

either for gross shipment or for individual packing convenience.Furthermore, itis 'a feature of this invention to provide a safety razorwith means for projecting a blade for cleaning or stropping purposes andwithdrawing or retracting the blade when the razor is not in use,thereby preventing exposure of the cutting edge. In the followingdescription of the operation, I will explain how and by what means thestrcture affords the above various advantages. l

In the shaving position shown in Fig. 4, the edges 28 of the slot coactwith the sides of the handle shank 22, to hold the blade holder tion,the disc 16 will hold the blade 7, in

such relation to the guard 6, as to be in effective shaving relationthereto, 'such relation being shown in Fig. 5. A f

When it is desired to adjust the blade holder into the plane of thehandle, the parts are adjusted. into the position shown in Fi s. 1 and5, by disconnecting link 30 and shi ing the blade holder as shown. Thisadjustment might, in itself, be a valuable and advantageous one apartfrom the adjustments to be presently described. However, the edge 8, ofthe blade 7, in this initial adjustment, is still in the same shavingposition as in Fig. 4, and would of course not be protected. However, itwill now be clear that the sl in sheath 24 permits the holder tobe'adjusted from the shaving position shown in Fig. 4, to the initialcollapsed position shown in Fig. 1. v v

Assuming' that the user had finished shaving, in the course of thisdescription, and wanted either to clean or strop the blade prior toputting it away, then, he would shift the blade holder into the positionshown in Figs. 3 and 7, in which position the blade is projectedsufficiently to be cleaned of all lather or soap and is equally adaptedto be stropped.

After the blade has been cleaned and stropped, then, the user can adjustthe holder into the position shown in Figs. 2 and 6, in which positionthe blade is retracted into the holder soas to be aforded the protectionof the latter as a case therefor, the cutting edge being clearly out ofa position for contact with anything.

Thus it will be seen that theuser need never remove the blade either forcleaning or stropping purposes, and it will now be clear how therelative movement of the holder and handle serves, through the disc 16,andthe pin and slot connection, to correspondingly shift the blade intothe various positions shown.

It may be desirable to briefly recapitulate the operation in detail.

In shifting the holder and handle from the Fig. 1, to the Fig. 2,position, the disc 16 is positively actuated and by reason of the factthat the blade 7 is guided by the flanges 2, I insure a positive andunvariable parallel relation between the guard 6 and the cutting edge 8,irrespective of the extent of movementof the blade 7. Further, by reasonof the constant engagement of the pin 18 with slot 9, the blade 7 willbe positively held in its adjusted positions. y

When the holder and handle are relatively adjusted from the Fig. 2 tothe Fig. 3, position, the disc 16 is actuated in the reverse dif rectionto that illustrated in Fig. 2.

It is also informative to state that while the leaf 11 firmly engagesthe blade 7 and holdsthe latter sufiiciently ti htly against the baseplate 1 to prevent wo bling move/ ment of the blade,-still, thisengagement isV not sufficient to burdensomely resist adjust-- ment ofthe blade to the various positions shown and is only suiiicient to actas an advantageous drag to prevent a too free movement of the holder andhandle. Thus, in

order to make the various adjustments shown in Figs. 2 and 3, it is notnecessary to first release the leaf 11.

It is believed that the invention will be fully understood from theforegoing description, and while I have hereinv shown and described onespecific form of my invention, Ido not wish to be limited thereto exceptfor such limitations as the claims may import.
